STM32 MCUs Products

I am using STM32H745 Discovery kit. I was running the example provided for UART but unable to see any message in Serial terminal. Checked on CRO but I am unable to see any data transmitted from TX pin (PB10).

I have directly connected the Tx of board to Rx of my computer and Rx of board to Tx of computer through the TTL to USB converter. I also checked the Tx and Rx of the board on DSO but was not able to see any data.

QSPI HOLD remains asserted when switching from 1-line to 4-line mode

If I execute all OSPI commands with either DataMode set to HAL_OSPI_DATA_1_LINE or set to HAL_OSPI_DATA_4_LINES then everything behaves as expected. If I first execute a command with DataMode set to HAL_OSPI_DATA_1_LINE, then the Data[3]/HOLD line re...

STM32H7 why is Dcache faster than DTCMRAM ?

I am benchmarking Stm32h7 processor on floating point operations and using CYCCNT to measure the performance difference .I placed my function in ITCM-RAM. which is just a function that does double math multiplication 10,000 times, the 4 variables use...
